[Python] invalid command name 'main:app' when I execute "uvicorn main:app --reload"

Good afternoon! When I try to execute the command uvicorn main:app --reloadfor start my local server, the VSCode terminal throws the error invalid command name 'main:app'. The code below imports a variable from the pipeline of the generative AI model using FastAPI to estabilish a route for the generated responses. I guess the trick is in the "main" method that imports uvicorn library and use it to run the app, apparently the code is right but maybe I missed something.

#main.py
from fastapi import FastAPI
import sys
import os

# Adds the root directory to sys.path
sys.path.append(os.path.dirname(os.path.abspath(__file__)))

from src.inference.pipeline import generate_response
app = FastAPI()

@app.post("/predict")
def predict(input_text: str):
response = generate_response(input_text)
return {"response": response}

if __name__ == "__main__":
import uvicorn
uvicorn.run(app, host="0.0.0.0", port=8000, reload=True)
